"The defining moment for me came shortly after Palin and her family stepped down from the stage to uproarious applause, looking happy enough to throw a whole library full of books into a sewer. In the crush to exit the stadium, a middle-aged woman wearing a cowboy hat, a red-white-and-blue shirt and an obvious eye job gushed to a male colleague — they were both wearing badges identifying them as members of the Colorado delegation — at the Xcel gates.

I stared at her open-mouthed. In that moment, the rank cynicism of the whole sorry deal was laid bare. Here's the thing about Americans. You can send their kids off by the thousands to get their balls blown off in foreign lands for no reason at all, saddle them with billions in debt year after congressional year while they spend their winters cheerfully watching game shows and football, pull the rug out from under their mortgages, and leave them living off their credit cards and their Wal-Mart salaries while you move their jobs to China and Bangalore.

And none of it matters, so long as you remember a few months before Election Day to offer them a two-bit caricature culled from some cutting-room-floor episode of Roseanne as part of your presidential ticket. And if she's a good enough likeness of a loudmouthed Middle American archetype, as Sarah Palin is, John Q. Public will drop his giant-size bag of Doritos in gratitude, wipe the Sizzlin' Picante dust from his lips and rush to the booth to vote for her. Not because it makes sense, or because it has a chance of improving his life or anyone else's, but simply because it appeals to the low-humming narcissism that substitutes for his personality, because the image on TV reminds him of the mean, brainless slob he sees in the mirror every morning.

...The great insight of the Palin VP choice is that huge chunks of American voters no longer even demand that their candidates actually have policy positions; they simply consume them as media entertainment, rooting for or against them according to the reflexive prejudices of their demographic, as they would for reality-show contestants or sitcom characters. Hicks root for hicks, moms for moms, born-agains for born-agains. Sure, there was politics in the Palin speech, but it was all either silly lies or merely incidental fluffery buttressing the theatrical performance. A classic example of what was at work here came when Palin proudly introduced her Down-syndrome baby, Trig, then stared into the camera and somberly promised parents of special-needs kids that they would 'have a friend and advocate in the White House.' This was about a half-hour before she raised her hands in triumph with McCain, a man who voted against increasing funding for special-needs education.

...It is worth noting that the same criticisms of Palin also hold true for two other candidates in this race, John McCain and Barack Obama. As politicians, both men are more narrative than substance, with McCain rising to prominence on the back of his bio as a suffering war hero and Obama mostly playing the part of the long-lost, future-embracing liberal dreamboat not seen on the national stage since Bobby Kennedy died. If your stomach turns to read how Palin's Kawasaki 704 glasses are flying off the shelves in Middle America, you have to accept that Middle America probably feels the same way when it hears that Donatella Versace dedicated her collection to Obama during Milan Fashion Week. Or sees the throwing-panties-onstage-"I love you, Obama!" ritual at the Democratic nominee's town-hall appearances.

So, sure, Barack Obama might be every bit as much a slick piece of imageering as Sarah Palin. The difference is in what the image represents. The Obama image represents tolerance, intelligence, education, patience with the notion of compromise and negotiation, and a willingness to stare ugly facts right in the face, all qualities we're actually going to need in government if we're going to get out of this huge mess we're in.

Here's what Sarah Palin represents: being a fat fucking pig who pins "Country First" buttons on his man titties and chants "U-S-A! U-S-A!" at the top of his lungs while his kids live off credit cards and Saudis buy up all the mortgages in Kansas.

The truly disgusting thing about Sarah Palin isn't that she's totally unqualified, or a religious zealot, or married to a secessionist, or unable to educate her own daughter about sex, or a fake conservative who raised taxes and horked up earmark millions every chance she got. No, the most disgusting thing about her is what she says about us: that you can ram us in the ass for eight solid years, and we'll not only thank you for your trouble, we'll sign you up for eight more years, if only you promise to stroke us in the right spot for a few hours around election time."
